223003404 - E7030 AIRBAG - DESCRIPTION
Description
The car is fitted with an electronically-controlled safety system which, in the case of a front-end crash of some severity, activates the driver''s and passenger''s Air Bags.In the case of a side impact of a certain magnitude, the Side Bag and the Head Bag, located in the front door pillar are activated (only on the side where the impact occurred).An electronic control unit manages the entire system by controlling all the components and activating the restraint systems (Air Bags) as necessary.There is an accelerometric sensor on the two front door pillars which, in the case of a side impact, transmits a signal to the control unit.This signal is also processed inside the control unit which, as a result, decides on the operation of the Side Bag on the side where the impact has taken place.The control unit is located under the centre console and is rigidly fixed to the bodyshell: in this way the deceleration sensors located inside it are close to the centre of gravity and detect deceleration for the entire vehicle accurately.The driver''s Air Bag module is located in the centre of the steering wheel; it is fitted on a tilting plate which enables the horn to be operated. The plate houses a metal container which holds the folded airbag and a gas generator that inflates the bag.A clock spring device allows the airbag module connection leads to turn with the steering wheel without the risk of breakage.The passenger airbag is located on the facia, above the glove compartment., and is fastened directly to the car crossmember via a special bracket.The passenger Air Bag can be deactivated manually by means of a specific switch.The switch, which is ignition-activated, is located in the dashboard, on the passenger side and is accessible only with the door open. With the key in the OFF position, the control unit also controls the operation of the special ''passenger Air Bag disabled'' warning light.The side Air Bag is housed in the outer part of the front seat. The sensor is located in the centre pillar.The control unit comes with a self-diagnostic function.
